Heterogeneous Nucleation as a Mechanism for Igneous Cumulate Formation without Buoyancy

Lydéric France Journal of Petrology, Volume 67, Issue 9, September 2026, egag073 Voir en ligne : https://doi.org/10.1093/petrology/egag073 Cumulate rocks are generally interpreted as the products of crystal-melt segregation driven by buoyancy-related processes such as crystal settling, mush compaction, or melt percolation. Yet, the potential role of crystal nucleation processes in generating early crystal-melt heterogeneities remains

Regolith thickness across the Borealis Planitia region of Mercury

Joulaud M., Allemand P., Flahaut J., Füri E. Planetary and Space Science, Article n°106338, Volume 282, November 2026 Voir en ligne : https://doi.org/10.1016/j.pss.2026.106338 Mercury’s surface is covered by regolith produced by meteoritic bombardment, recording the planet’s impact and geological history. In this study, we assess the regolith thickness of the Borealis Planitia region (−72°E, 66°N),
